It operates around 30 per cent of India's domestic crude oil production. Through its affiliates, Cairn India has been operating for close to 20 years playing an active role in developing India's oil and gas resources. Till now Cairn India has opened four frontier basins with over 40 discoveries out of which 31 are in Rajasthan alone.
